"Innocents were killed, but I don't think they were killed by the Israelis."
To me, some of the bodies they showed appeared to have been dead for several days. I think they are "recycling" the dead.
There was another blog posted on FR that I saw that talked about how many of the bodies seemed to be in rigor. Also, the "rescuers" tee shirts are bleached white; just how long would that last while digging into rubble to retrieve bodies? About 5 minutes, maybe.
